Question:

Suppose you want to predict some future value of y when x = xusing the prediction equation ŷ = β̂o + β̂1x. The error of prediction will be the difference between the actual value of yp and the predicted value ŷ, i.e.,

Error of prediction = yp - ŷ

a. Explain why the error of prediction will be normally distributed.

b. Find the expected value and the variance of the error of prediction.
